DEMOUNTABLE RIM.

Application flfled October 11, 1921.

To all 'whom z't may camera:

Be it known that GARRIE C. RAMSEY, a citizen of the United States,residing at Lebanon, in the county of Hunterdon and State of New Jersey,has invented certain new and useful Improvements in Demountable Bims, ofwhich the following is a specification.

This invention has relation to certain new and useful improvements in ademountable rim and has for its primary object the provision of a deviceof this character which may be readily applied to the conventional formof Wheels and used With the ordinary tires without the necessity ofaltering the construction thereof.

The invention has for another object the provision of a demountable rimof the character stated in which will be included a plurality of rimengaging members and means mounted on the Wheel felly and adapted to beoperated by a sliding member to throw the looking members outwardly overthe edge of the removable rim section or tire supporting members tosecure the latter in position upon the rim or felly of the Wheel proper.

The invention has for a further object the provision of a demountablerim of the character stated in which all of the pivoted looking memberscarried by the sliding member may be operated therewith for the pur-lpose of moving the looking members to operative and inoperative positionfor the-purpose of holding the rim in proper place upon the felly or topermit removal of the tire and the tire rim.

The invention has for a further object the provision of a demountablerim of the character stated Which will be composed of the minimum numberof parts, of simple construction and operation and comparativelyinexpensive as well as highly eflicient in use.

lVith the foregoing and other objects in view as will appear as thedescription proceeds, the invention consists in the novel con-'struction, combination and arrangement of Serial No. 507,108.

ing the lock members and sliding members in inoperative position.

Figure 3 is a detail view of the sliding looking member removed.

Figure 4 is a detail cross-sectional View on the plane of line 4-4 ofFig. 1 with the parts shown on an enlarged scale.

Figure 5 is a similar view on the plane of line 5-5 of F ig. 1, lookingin the direction indicated by the arrows.

Figure 6 is a detail cross-sectional view on the plane of line 6-6 ofFig. 1, looking in the direction indicated by the arrows.

Referring more to the drawings in which similar reference charactersdesignate corresponding parts throughout the several views, 1 indicatesthe sliding member which is in the form of a ring adapted to be mountedupon one side of the Wheel felly 2 of the oonventional form of Wheel 3,as shown in the drawings. The ring 1 has a plurality of spaced elongatedslots 4 adjacent its outer edge and parallel with the said edge, as Willbe clear from the drawings. This ring 1 has a plurality of lookingmembers 5 pivoted to the outer face of the ring 1 near the inner edgethereof by suitable pivot members 6 portions or inner ends of saidlooking members 5. The looking members 5 have elongated slots 7extending along one longitudinal edge portion thereof and slightlycurved, as shown clearly in the drawings, particularly Figs, 1 and 2.The stationary guide pins 8 projecting from the side of the Wheel felly2 are so positioned that each guide pin 8 projects through one of theslots 4 of the ring 1 and the slots 7 of the looking member 5 pivoted tothe ring 1 adjacent said slots 4, as shown in Figs. 1 and 2 of thedrawings. The removable rim 9 carries thereon the usual inflated tire 10is adapted to be seated upon the solid band or iron 11 which has oneside turned inwardly to provide a flange for receiving one side of therim 9. An angular lever 13 is pivoted at its bent portion as shown inFigs. 1 and 2 of the drawing on a headed pin 1.4 formed at the end of ashank 15 which is carried by a collar 16. This collar 16 is adapted tofit around one of the spokes of the Wheel 3 adjacent the felly 2 thereofand is held in clamped position thereon at 17 as shown in Fig. 6 of thedrawings.

The shorter arm of the angular lever 13 is provided With an elongatedslot 18 adjaextended through the narrow corner cent its vforward end andslidably received therein is a pin 19 which is seoured to the ring 1,the purpose of which Will hereinafter be more fully described., Carriedon the felly 2 of the Wheel 3 and adjacent the ring 1 is mounted anangular looking member 21. This angular looking member 21 is mounted onthe felly 2 by having its base 22 fitting over a threaded bolt 23 whichextends up- Wardly from the felly 2 and is inserted therein, and a looknut 24 is threaded upon the threaded end of the lbolt 23 for holding theangular looking member 21 in proper position upon th`e 'wheel felly 2.The upper forward end 25 of the angular looking member 21 is cut away toform a seat or pocket 26 for engagementwith the free end of the Jangularlever 18 When the same is in position as shown in Fig. 1 of thedraWings.

In use after a'rim and inflated tire carried thereby is `placed upon thefelly band 11 of the Wheel, the slidable ring 1 and the looking members5 pivotally mounted thereon are in position as shown in Fig. 2 of thedrawingis, the sliding ring 1 and the looking fingers 5 pivotallymounted -thereon are caused to move 'in the manner as shown in Fig. 1 of*the drawings whereby they are Vnow in a looked position. This ``isacoomplished by pulling do'WnWa-rdlyion' the handle of the angular lever13 Wherebytheslot 18 formed in the short arm of the same will Vcause thevipin 1-19 carried by the ring 1 to move in a olookwise direction and asthe ring 1 moves in lsuch a direction and slides on the side faces ofthe Wheel felly 2, the stationary guide 'pins 8 carried by the felly 2and extending through the registering slots 4 and 7 formed in thesliding ring 1 and looking members' respeotiVe-ly will cause the lookingmembers 5 to move outwardly and engage the rim 9 of the opposite side asis acoomplished by the flange 12 formed upon the felly band 11 on theopposite side. The rim 9 and tire 10 will thereby be caused to boseourely held upon the felly of the Wheel and to further assure the rim9 of being held in a looked position the free end of the angular lever13 -is oausednto beheld in engagement Wit-lrthe underside of the forwardupward end 25 of the angular looking member 21 there-by preve-ntingtheacoidental'movemont of the' looking fingers or members 5 fromengagement With the rim 9.

i To release or remove the rim and tire carried thereby from a lookedposition upon the Wheel felly, the lever 13 is released from the lookingmember 21 and is moved in a revorse direction whereby the ring 1 willmove in a'counterolockwise direction and Will cause the looking members5 to move in'wardly therewith so as to release the looking members 5from engagement with the rim 9.

It is believed that the complete construction and operation of thisinvention may now be readily understood without further detaileddescription. Attention may be direoted to the fact, however, that whilethe preferred embodiment of the invention has been shown and described,it is to be understood that I do not Wish to be limited thereto and thatminor changes may be made in the construotion and arrangement of partsWithin the scope of What is claimed Without departing fromthe spirit ofythe invention.

What I 'olaim is:

1. A demountable rim securin'g means comprising the combination with aWheel felly and a rim member removably mounted thereon, of a ringslidably mounted upon the side face of the said felly, looking memberspivotally mounted at one end to the said ring, said ring and lookingmembers provided with registering slots, means carried by the said fellyand extending through the registering slots in said ring and lookingmembers for causing the operation of the looking members.

2. A demountable rim securing means comprising the combination With aWheel felly and a rim member demountably positioned thereon',-of ay ringcarried on one side of the felly and adapted for limited slidingmovement in either direction thereofin, locking members pivotallymounted on the said ring, said rin'g and looking members provided Withregistering slots, stationary pins carried by said felly and extendin'gthrough the registering slots formed in the said ring and lookingmembers for causing the said looking members to' move into operative orinoperative position, and means associated with the sliding ring forholding the same and the looking ring in a looked position.

3. A de'mountable rim seouring means compfising the combination With awheel felly and a rim member removably mounted thereon, of a slidablering carried on the side face of the said felly, looking Vmemberspivotally mounted at one end to the saidslidable ring, said slidablerin'g and llooking members pivotally mounted thereon pr'ovided withregistering slots, stationa'ry'pins carriedby the side of lthe felly andextending through the registering slots in the ring and looking membersto cause the inward and outward move-mont of the said looking membersupon the slidable ring, a lever pivoted at one end to thel said slidablering vvfor moveing the same and the looking members carred thereby intooperative and inoperative position, and means on .the felly for holdingthe lever and the slidable ring and looking members in a looked'position.
